"... with Brother lasers is the toners isn't re-fusable ..."

Actually I think the problem is as someone else has suggested, i.e. that the
required fuser temp is much higher. I have a Brother MFC-8500, probably
about 10 years old now, still works fine but not very well for TT. Prints
look fine on paper, even for large dark areas, but it's hard to get the
toner to stick to a copper clad board and the toner isn't dense enough to
completely block out the etch acid. Same problem making transparencies for
photo resist masks.
